Congress: Wastes from the Extraction and Beneficiation of Metallic Ores, Phosphate Rock, Asbestos, Overburden From Uranium Mining, and Oil Shale ( EPA 1985a). In July 1986, EPA made a regulatory determination that regulation of extraction and beneficiation wastes under Subtitle C was not warranted (51 FR 24496; July 3, 1986).
Beneficiation of a lowgrade iron ore was investigated by combination of the lowintensity magnetic separation and reverse flotation methods. The main constituents of the representative sample were Fe FeO CaO SiO2 and S based on the Xray fluorescence titration and Leco analysis methods.
This chapter focuses on treatment methods for goldbearing ores. Flotation is the best method for recovery of gold from base metal ores and goldcontaining PGM (platinum group metal ores. Excluding gravity preconcentration, flotation remains the most costeffective beneficiation method.
